Mitral Annular Calcification: Natural History, Prognosis, and Clinical Outcomes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Mitral annular calcification (MAC) is a chronic and progressive degenerative process characterized by calcium and lipid deposition of the mitral valve annulus. We sought to describe the natural history of patients with MAC with and without mitral valve dysfunction (MVD). Methods: We conducted an observational study of patients with an echocardiogram-based diagnosis of MAC from 2006-2023. Patients were matched by age and sex in a 1:1 ratio to patients without MAC. We collected baseline clinical, echocardiographic, and computed tomography data. The primary end point was all-cause mortality. We also report predictors of mortality in patients with MAC and MVD. Results: We included 15,372 patients in the analysis: 7686 with MAC (median age, 76 years [68-84], 58% women) and 7686 without MAC matched by age and sex. Patients with MAC had higher rates of comorbidities, cardiovascular risk factors, MVD, and multivalvular heart disease (aortic stenosis/regurgitation and tricuspid regurgitation) relative to patients without MAC (all Conclusions: Ten percent of patients with MAC have clinically significant MVD, with mitral regurgitation being more common than mitral stenosis. The presence of MVD is associated with significantly increased mortality in patients with MAC.
